OVERVIEW
Zero-Sum Heart has some pretty heavy stuff—like self-harm, violence, and gore. But don’t freak out; the art is kinda stylized, so it’s not super graphic or anything.
The story dives into some serious topics too like stalking harassment and messed-up relationships both family and romance. There’s murder and suicide too, which can hit hard.
And just a heads up: when the main character tries to connect with others while under magical influence, it gets a little murky with consent, which can be really uncomfortable. Honestly, it’s a lot to unpack, and it’s definitely not for the faint of heart. You may also be interested in the game Cryowakers.
